## Questions

### Who runs investment decisions at Merlin Nexus?

Investment decisions are led by Managing Partner Dominique Sémon, who founded the firm in 2005. Partner Naveed Siddiqi is also a key decision-maker and has been with the firm since its early years. The small senior team structure means investment committee decisions are tightly centralized.

### What types of securities does Merlin Nexus typically buy?

The firm focuses on PIPEs, pre-IPO convertible notes, and structured equity in late-stage life science companies. Merlin Nexus does not operate as a venture capital firm writing early-stage seed checks; its target window is the 12–24 months before an anticipated public listing or M&A event.

### Does Merlin Nexus co-invest alongside other crossover funds?

Yes. Merlin Nexus regularly participates in syndicated rounds alongside larger crossover investors such as RA Capital, Perceptive Advisors, and OrbiMed, particularly for US-bound biotech IPOs. Its value to syndicates is often the European sourcing angle for issuers that need transatlantic placement.

### Which geographies does Merlin Nexus cover?

The firm maintains a dual focus on the United States and Western Europe. Known portfolio activity includes European biotech issuers cross-listing on NASDAQ, as well as US-based therapeutic companies seeking crossover financing ahead of a domestic IPO.

### Which sectors does Merlin Nexus explicitly avoid?

Merlin Nexus is a pure healthcare investor and has no publicly disclosed activity in sectors outside biotechnology, specialty pharmaceuticals, medical devices, and diagnostics. The firm does not invest in healthcare services, health IT, or non-life-science verticals.
